Hello, last time I got fantastic help with my seedlings but now I have different problems und different plants agin and don't know if it's bad or normal.
I am a first time grower and my plants are in coco coir with 30 percent perlite. I use biobizz grow, activera and calmag and use it with tap water with a starting ec of 0.3. I feed my plants phed water with a of around 6 and an ec of 0.5 - 0.8. Now over night one plant got brown leaf Tipps, the other has the tips of the serated edge rolled upwards, am the third one has some weird discoloring. What do I do wrong and what do my plants have?

Bit more info, I use a 80cm x 80cm grow tent with a 180 Watt led panel on 80 percent around 30 - 40cm above the plants. Rh is around 50-65% and tells between 20c to 24c.

Would be nice if someone can help me IMG_20210424_153142.jpgIMG_20210424_153242.jpgIMG_20210424_153658.jpg

one possibility is that your light may be too close and the tiny root system cant keep up with the nutrient intake i sometimes have it with even bigger plants see if raising your lights to 50cm+ works

Bump.
The one plant looks worse than yesterday. Is it a cal or mag deficiency? Or something else, someone an idea? IMG_20210425_124040.jpg
